By default, Google retains your Gemini conversation data for up to 3 years, though you can change this retention period or delete your history in your account settings.
A 3-year default retention period is significantly longer than many users would expect for an AI chat service, meaning years of personal interactions may be stored and accessible.
A 3-year default retention period requires scrutiny under GDPR Article 5(1)(e) storage limitation principle and CPRA data minimization requirements. Compliance teams should assess whether this retention period can be justified by the stated purposes and whether adequate contractual controls exist for Workspace deployments.

When you use Gemini, Google collects your conversations, location, device data, and feedback, and may use this to train AI models and allow human reviewers to read your chats. Your conversation history is stored for up to 3 years by default, even if you delete it from your view, with some data retained for up to 18 months in separate review logs. You can turn off Gemini Apps Activity at myaccount.google.com to stop your conversations from being used for AI model training.
